If you browse through the pages, you have to come across large-scale images of cities, arranged by continent and region. Many of these photos are taken by passionate visitors, but the local population also makes contributions. Whatever their origin, they take into account cosmopolitan trends promoted by global cultures. That fact causes convergence in styles and ideas, although the appearance of things is naturally differentiated by the peculiarities of geography. The images chosen for inclusion in the World Atlas of street photography are selected by the traditional obligations of the street genre itself , which is appreciated for its credibility as an urban witness. They have been selected because they are thought-provoking images of our urban landscapes.
